The starting price is listed at $125, the oak cabinet is dirty and a little banged-up looking, but eminently saveable! The seller claims it works (of course, with a non-Edison Diamond Disc record on the turntable).

Local pickup only.
The cabinet is the type with the lip at the top edge of the turntable compartment. No grille present.
The "lever-type" mute ball actuator is present.
The motor-plate has no "fancy" corner pinstriping present, and the start/stop lever configuration appears to be the 2nd type used on the mechanism.
All of this suggests (to me) that it may have been produced somewhere in the middle of the run. I've messaged the seller for the serial number, if he responds, I'll update this post.
If I were close enough, I would buy it without hesitation.
Best,
Fran
